Answer:

Gas

Explanation:

The properties of the three states of matter are:

solid : fixed shape, fixed volume, high density as the intermolecular forces are strong and the particles cannot move here there. Only vibrations are possible.

Liquid: Fixed volume but shape depends upon the container, density lower than solid but higher than air.

Gas: Not fixed volume and not fixed shape also. The density is least among the three states of matter. There are leas strong force of interactions between molecules. the thermal energy is highest among the three states of matter.

Thus answer is gas.

A 25.00-mL aliquot of a nitric acid solution of unknown concentration is pipetted into a 125-mL Erlenmeyer flask and 2 drops of
Semenov [28]

Answer:

0.0611M of HNO3

Explanation:

<em>The concentration of the NaOH solution must be 0.1198M</em>

<em />

The reaction of NaOH with HNO3 is:

NaOH + HNO3 → NaNO3 + H2O

<em>1 mole of NaOH reacts per mole of HNO3.</em>

That means the moles of NaOH used in the titration are equal to moles of HNO3.

<em>Moles HNO3:</em>

12.75mL = 0.01275L * (0.1198mol / L) = 0.0015274 moles NaOH = Moles HNO3.

In 25.00mL = 0.025L -The volume of the aliquot-:

0.00153 moles HNO3 / 0.025L =

<h3> 0.0611M of HNO3</h3>

Match: Substance ....... Definition Lewis acid A. Provides H+ in water Bronsted-Lowry base B. Provides OH - in water Arrhenius b
Igoryamba

Answer: F.    Electron pair acceptor

Explanation:

A Lewis acid can be properly defined as any substance such as  H+ (hygrogen ion) that can accept a pair of electron.

While a Lewis base is any substance such as (OH-) that can donate a pair of electron.

In the neutralization reaction between an acid ( H+ ) and a base (OH-). Hydrogen ion (H+ ) is the Lewis acid because it accepts an electron pair from (OH-).

Other examples of Lewis acid are;  Mg2+, K+

Zinaida [17]

Answer:

nucleic acid

Explanation:

ATP -

In the living organisms it is a very important source of energy for various biological processes like chemical synthesis , nerve impulse propagation and contraction of muscles , is referred to as Adenosine triphosphate ( ATP ) .

ATP is a nucleic acid , which is a single chain nucleotide , which is composed of ribose sugar along with three phosphate groups .

ATP is also known as the battery of the cell.

Hence , from the given information of the question ,

The correct term is nucleic acid.
